Running an SEO contest
Regular SERP snapshots, moderation, anti-cheat and transparency while the contest runs.
Track the ranking
Schedule snapshots (weekly or daily) of positions with a rank tracker and keep the screenshots. Multi-platform measurement, as in the algorithmic pumpkins contest, requires a single protocol.
Moderate and sanction
Plan a jury, a reporting channel and graduated sanctions for spam, negative SEO or hacking third-party sites.
Communicate regularly
Newsletters, public leaderboards and phase announcements sustain engagement and earn natural mentions.
